Ah, the weekly "which SSD should I buy" thread has devolved into the Garbage Collection vs. TRIM vs. OS X doesn't support this discussion. Happens with 1.0 probability everytime.
There's TONS of threads here discussing this. Most folks don't have a clue what they're talking about.
Some of us have researched this extensively, including myself. There's no one perfect answer. For me, the 160 GB Intel X25m G2 was the best choice. Everything you want to know about (lack of) write degradation on this drive can be found here. This discussed the V-version of the Intel drive, but the analysis is spot-on.

BTW, worst-case for those drives that don't manage cell cleanup, you see a small degradation (30-40%) in write speed. Most of the time, you're reading off these drives, so my bet is most folks wouldn't even notice a difference. The whole TRIM/degradation/GC argument is frankly "much ado about nothing". The performance increases of SSDs over traditional HDs is so large, any SSD will be a notable improvement, even a fully-write-speed-degraded generation 1 SSD.
